Search for package(s) by searching the expression in name, description, short description. What exact fields are being searched by default varies in each tool. Mostly options bring tools on par.

emerge -S

Upgrade Packages - Install packages which have an older version already installed

pacman -Syu

yum update

apt-get upgrade

rug update

zypper update zypper up

emerge -u world

Upgrade Packages - Another form of the update command, which can perform more complex updates -- like distribution upgrades. When the usual update command will omit package updates, which include changes in dependencies, this command can perform those updates.

pacman -Syu

yum distro-sync

apt-get dist-upgrade

zypper dup

emerge -uDN world

Reinstall given Package - Will reinstall the given package without dependency hassle.

Mark a package previously installed as a dependency as explicitly required.

pacman -D --asexplicit

aptitude unmarkauto

emerge --select

Install package(s) as dependency / without marking as explicitly required.

pacman -S --asdeps

emerge -1

Package information management

Get a dump of the whole system information - Prints, Saves or similar the current state of the package management system. Preferred output is text or XML. One version of rug dumps information as a sqlite database. (Note: Why either-or here? No tool offers the option to choose the output format.)

(see /var/lib/pacman/local)

(see /var/lib/rpm/Packages)

apt-cache stats

rug dump

emerge --info

Show all or most information about a package. The tools' verbosity for the default command vary. But with options, the tools are on par with each other.

Search for package(s) by searching the expression in name, description, short description. What exact fields are being searched by default varies in each tool. Mostly options bring tools on par.

pacman -Ss

zypper search zypper se [-s]

emerge -S

Lists packages which have an update available. Note: Some provide special commands to limit the output to certain installation sources, others use options.

rug packages

zypper packages

emerge -ep world

Displays packages which provide the given exp. aka reverse provides. Mainly a shortcut to search a specific field. Other tools might offer this functionality through the search command.

apt-file search <filename>

rug what-provides

zypper what-provides zypper wp

equery belongs (only installed packages); pfl

Display packages which require X to be installed, aka show reverse/ dependencies. rug's what-requires can operate on more than just package names.

rug* file-list

IN PROGRESS

equery files

List all packages that require a particular package

${EDITOR} /etc/apt/sources.list

layman

Add an installation source to the system. Some tools provide additional commands for certain sources, others allow all types of source URI for the add command. Again others, like apt and yum force editing a sources list. apt-cdrom is a special command, which offers special options design for CDs/DVDs as source.
